Title: Method and apparatus for optical rf amplitude equalization
Inventor: BRANDSTETTER ROBERT W
IPC: G02F1/01
Filed: 1987-04-30
Granted: 1990-11-20
Abstract: ABSTRACT OF THE DISCLOSURE          Amplitude equalization of a distorted multifrequency signal is accomplished by acousto-modulating the signal with a coherent light beam and focusing a resultant image on a Fourier plane where the frequency components of the image are spatially distributed. A control array, positioned in the plane, contains adjacent elements having optical filtering properties variable with respect to each other thereby selectively altering the optical amplitude of each image frequency component passing through the elements. The resultant transformed image then undergoes conversion to an electrical signal having its amplitude equalized relative to the distorted input signal.

Abstract: Phase errors that occur when a dithered ring laser gyroscope enters its deadband are measured, and a correction is applied to the output of the ring laser gyroscope to compensate for these phase errors. The counterpropagating beams in a ring laser gyroscope are heterodyned to produce a pair of quadrature heterodyne signals that indicate the angular output of the laser ring laser gyroscope. The phase angle error between one of the heterodyne signals and either the sum or difference of the separate beam intensities is determined. The phase angle error signal is used to produce a control signal for adjusting the output of the ring laser gyroscope to correct for errors introduced at or near turnarounds in the dither cycle.
